To all whom it may concern: v

Be it known that. I; WILLIAM E. HANCQCK, a citizen of the; United Statesof Am rica, and resident oj f'Tulse, in the county of Tulsa 6 and Stateof Oklahommhave invented certain new and useful Improvements in GasBurners, of which the following is a specificetion. c p r This inventionrelatesto gesburners, and 10 has for an object the provision of novelmeans for feeding gas and steam to a fur.- neceythe steam acting toenrich the gas and produce qualities which will result in increasingeffectiye combustion of the fuel mixture as it, issues from jets ornozzles stationed Within the fire box of efurnace.

VA further object of this invention is to provide novel means forcontrolling" the mixture of gas. andsteam, and other means actuated bythe pressure of the steam for operating the controls of the steam and ga7 It is at further object of this invention to produce a self-regulatingfuel mixing and delivering apparatus in which the pressure of steamwithintheboiler of a furnace during its rise and fall will automaticallydiminish or increase the supply of gas and steam to the burners of thefurnace.

A still further object of this invention is to provide means forregulating the controls or valve of the steam and gas delivery pipes, inorder that the, mixture may be changed to make it richer or leaner,according togthe requirements in practice and the condition of gas beingconsumed 1 With the foregoing and other objects in view, the inventionconsists in the details of construction, and in the arrangement andcomb-ination'of parts to be hereinafter more 40 fully set forth-andclaimed.

been r we h ie J2; see which in the present embodiment o ,theiigsecured"therein by rstjing in, aprtur or is closed at one end by a plug 14 andthe said steam pipe has a branch 15 extending outwardly through the wallof the header and it is connected'to a branch 16 of a steam pipe 17 Theheader has hollow branches or extensions 18 to which'the pipes 9 areconnected for delivering fuel to the furnace. The steam pipe 13 has jets19 connected to it,

and these jets extend through the hollow.

branches of the header and preferably e:-:- tend slightly into the pipes9 in order that when steam is supplied to the ipe 13, it will act on andbe coinmingle with gas which is delivered through the header, as willpresently appear.

The pipe 17 leads to the source of steam supply such asthe furnaceboiler. and it supplies steam to thepipe 16 and to an extension 20thereof, which extension constitutes a support for a pressure actuatedmechanism 21 for controlling the valves of the steam and gas supplypipes, as will presently appear. The pressure actuated mechanism may bein the nature of adiaphragm or like device to be moved by the pressureof steam, and as these devices are well known in the art, it is believedthat a detail illustration or description thereof will be unnecessary.

Apost 22 may, of course, extend from within the pressure actuatedmechanism, and a lever 23 may be pivoted on the post and hinged as at24, to a bracket 25, supported in any appropriate way. The bracket hasabifurcated arm 26 constituting a guide for the lever 23. and the saidlever 1s supplied with an adjustable weight 27. the movement of whichweight on the lever w1ll' control the movement of the lever or requiredifferent pressures from within the pressure actuated'mechanism toeffect a movement of the lever. The bracket may be supported by a post28 having its lower end anchored to one of the branches 18 of theheader. although other means mav' be employed, for holding the bracketin operative relation to the other parts of the mechanism.

The steam delivery pipe 29 is coupled to the plpe l3, and a valve 30 ofsuitableconstruction may be interposed in the pipe to control thedelivery of steam to the header. The valve stem31 has anarm 32 securedon 1t, by which the stem is partially rotated when the arm isoscillated, and the said arm has 'apertures 33 to receive a' pivot 34 ofa link 35, so that when motion is communicated to'the link, the'said armwill be raised or lowered at its outer end, and the interior mechanismof the valve is such that this movement will open or close the ports ofthe valve to increase or diminishthe supply of steam to the header. 7

Thegas delivering pipe 36 is coupled to the header through a nipple 37,and the gas pipe is provided with a valve 38 simllar to the valve 30.The valve 38 is controlled by the oscillated arm 39 which is secured tothe valve stem 40, and the said arm 39 has motion imparted to it throughthe medium of a linked which is pivotally connected to the lever 23 andto the said arm. Provision tuated. by the pressure within the boiler.

As steam rises, the lever 23 is pressed upwardly, whereas upon thepressure dim1n ishing, the weight 27 will force the outer end of thelever downwardly and actuate the valves in a direction opposite to thatin I,

which they were actuated by the lifting of the lever 23, due to thepressure within the boiler. V I

The steam pipes 13 has branches 42 and 43 opposite the-steam jets 16,and these branches are closed by plugs 44, the removal of which willpermit access. to the interior of the steam nipples in order thatdeposits may be removed therefrom.

The head has lugs 45 which engage the tubular member and serve to holdit in place. a

The mechan sm ustdescribed will prove effective to maintain pressures inboilers sub stantially uniform when the, valves in the 7 gas and steamsupply pipes have been properly set for the needs of the particularboiler or furnace, for the valves and the valve operating mechanism willbe set to supply a maximum amount of fuel for a a predeterminedpressure, at which time. the steam actuated device, for operating thevalves will operate the valves to cause a diminishing flow of gasandsteam. Should given furnace until the steamy has reached the pressureof steam fall below a predetermined point, the weight will overcome thepressure of steam and cause an'opening or partial reopening of thevalves in order that the fueldelivered to the burners will be increased.By having the parts of the apparatus operate under what might be termedsensitive conditions, the pressure in the boiler could be maintainedpractically uniform and of course automatically, since i the actuationof the valves is practicallyautomatically accomplished,
